{"id":"DEBIAN-CVE-2021-29488","details":"SABnzbd is an open source binary newsreader. A vulnerability was discovered in SABnzbd that could trick the `filesystem.renamer()` function into writing downloaded files outside the configured Download Folder via malicious PAR2 files. A patch was released as part of SABnzbd 3.2.1RC1. As a workaround, limit downloads to NZBs without PAR2 files, deny write permissions to the SABnzbd process outside areas it must access to perform its job, or update to a fixed version.","modified":"2026-09-01T20:04:26.969716295Z","published":"2021-05-07T15:15:07.503Z","upstream":["CVE-2021-29488"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2021-29488"}],"affected":[{"package":{"name":"sabnzbdplus","ecosystem":"Debian:12","purl":"pkg:deb/debian/sabnzbdplus?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.2.1+dfsg-1"}]}],"versions":["0.4.11-1","0.4.12-1","0.4.9-1","0.5.0-1","0.5.0-2","0.5.2-1","0.5.3-1","0.5.4-1","0.5.5-1","0.5.6-1","0.6.10-1","0.6.14-1","0.6.15-1","0.6.2-1","0.6.4-1","0.6.6-1","0.6.7-1","0.6.8-1","0.6.9-1","0.7.11-1","0.7.13-1","0.7.16-1","0.7.18-1","0.7.2-1","0.7.20+dfsg-1","0.7.20-1","0.7.3-1","0.7.4-1","0.7.5-1","0.7.6-1","0.7.8-1","0.7.9-1","1.0.2+dfsg-1","1.0.3+dfsg-1","1.0.3+dfsg-2","1.1.1+dfsg-1","2.3.1+dfsg-1","2.3.2+dfsg-1","2.3.4+dfsg-1","2.3.6+dfsg-1","3.0.0~0git20200408+dfsg-1","3.1.1+dfsg-1","3.1.1+dfsg-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2021-29488.json"}},{"package":{"name":"sabnzbdplus","ecosystem":"Debian:13","purl":"pkg:deb/debian/sabnzbdplus?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.2.1+dfsg-1"}]}],"versions":["0.4.11-1","0.4.12-1","0.4.9-1","0.5.0-1","0.5.0-2","0.5.2-1","0.5.3-1","0.5.4-1","0.5.5-1","0.5.6-1","0.6.10-1","0.6.14-1","0.6.15-1","0.6.2-1","0.6.4-1","0.6.6-1","0.6.7-1","0.6.8-1","0.6.9-1","0.7.11-1","0.7.13-1","0.7.16-1","0.7.18-1","0.7.2-1","0.7.20+dfsg-1","0.7.20-1","0.7.3-1","0.7.4-1","0.7.5-1","0.7.6-1","0.7.8-1","0.7.9-1","1.0.2+dfsg-1","1.0.3+dfsg-1","1.0.3+dfsg-2","1.1.1+dfsg-1","2.3.1+dfsg-1","2.3.2+dfsg-1","2.3.4+dfsg-1","2.3.6+dfsg-1","3.0.0~0git20200408+dfsg-1","3.1.1+dfsg-1","3.1.1+dfsg-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2021-29488.json"}},{"package":{"name":"sabnzbdplus","ecosystem":"Debian:14","purl":"pkg:deb/debian/sabnzbdplus?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.2.1+dfsg-1"}]}],"versions":["0.4.11-1","0.4.12-1","0.4.9-1","0.5.0-1","0.5.0-2","0.5.2-1","0.5.3-1","0.5.4-1","0.5.5-1","0.5.6-1","0.6.10-1","0.6.14-1","0.6.15-1","0.6.2-1","0.6.4-1","0.6.6-1","0.6.7-1","0.6.8-1","0.6.9-1","0.7.11-1","0.7.13-1","0.7.16-1","0.7.18-1","0.7.2-1","0.7.20+dfsg-1","0.7.20-1","0.7.3-1","0.7.4-1","0.7.5-1","0.7.6-1","0.7.8-1","0.7.9-1","1.0.2+dfsg-1","1.0.3+dfsg-1","1.0.3+dfsg-2","1.1.1+dfsg-1","2.3.1+dfsg-1","2.3.2+dfsg-1","2.3.4+dfsg-1","2.3.6+dfsg-1","3.0.0~0git20200408+dfsg-1","3.1.1+dfsg-1","3.1.1+dfsg-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2021-29488.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"}]}
